oscP5 - oscEvent OscMessage

in Contributed Library Questions • 3 years ago

i want to set a incomming value like "theOscMessage.get(0).floatValue()" to an existing value.

a error message "Cannot find anything named "value-name"

here is my code

float position; // value for function
/* incoming osc message are forwarded to the oscEvent method. */
void oscEvent(OscMessage theOscMessage) {
// check if theOscMessage has the address pattern we are looking for.
if(theOscMessage.checkAddrPattern("/FADER 1") == true) {
// check if the typetag is the right one.
if(theOscMessage.checkTypetag("f")) {
float OSCvalue = theOscMessage.get(0).floatValue(); // get the second osc argument
println(" values: "+OSCvalue);
position = OSCvalue;
return;
}
}
}

what is wrong with the value?

from the code snippet you provided i cant see anything wrong. testing with the following code works (osx 10.5, java 1.5, processing 1.1)

import oscP5.*;
import netP5.*;
OscP5 oscP5;
NetAddress myRemoteLocation;
void setup() {
size(400,400);
frameRate(25);
oscP5 = new OscP5(this,12000);
myRemoteLocation = new NetAddress("127.0.0.1",12000);
}
void draw() {
background(0);
}
void mousePressed() {
OscMessage myMessage = new OscMessage("/FADER 1");
myMessage.add(123.1); /* add a float to the osc message */
oscP5.send(myMessage, myRemoteLocation);
}
float position; // value for function
void oscEvent(OscMessage theOscMessage) {
if(theOscMessage.checkAddrPattern("/FADER 1") == true) {
if(theOscMessage.checkTypetag("f")) {
float OSCvalue = theOscMessage.get(0).floatValue();
println(" values: "+OSCvalue);
position = OSCvalue;
return;
}
}
}

the error message you get seems to be thrown by processing itself (i am assuming here after a quick google search).

i've found my mistake. i want to use the " float OSCvalue " at a class and the value is declared in oscEvent. so i become the error message. i've changed the float OSCvalue to global value and now it works.

what's up with a more complex example how to use receive incomming messages for the oscP5 library?

an example with a class (graphics or something) controlled by incomming osc events or something?

greetings, paul vollmer
